摘　　要：将试井解释中的无量纲解释图版拟合方法引入电缆地层测试器的资料解释 ,在考虑管线储存和表皮效应的条件下导出了半球形渗流的电缆地层测试器解析解 ,制作了无量纲解释图版。根据图版 ,可以利用测试早期数据进行渗透率的解释。The fitting technique of dimensionless interpretation chart in well testing is introduced into the data interpretation of wireline formation tester. The analytical solution of wireline formation tester in hemi-spherical percolation flow through porous media is derived and the dimensionless interpretive chart is set up with flow line storage and skin effect considered. According to the chart, the early data of the well testing can be used for interpretation of formation permeability.
